Faster WiFi

by Ricardo C
This article relates to Wi-Fi speeds. A team of Japanese researchers has just broken the record for wireless data transmission in the terahertz range. This is 20 times faster than most current Wi-Fi connections. The researchers focused on an unregulated part of the electromagnetic spectrum between 300GHz and 3THz. Using these frequencies the researchers were able to develop hardware capable of transmitting at 3Gb/s  at frequencies up to 542GHz which is about 20 times faster than current Wi-Fi connection. According to the article this is just a concept and terahertz Wi-Fi would probably only work over short distances.

I think this relates to previous topics in class such as mobile devices. We discussed that databases for mobile devices are growing because the mobile device has become popular but it has its limitations such as computing power and narrow bandwidth. I found this article interesting because this could take care of the bandwidth limitation and it might give mobile devices chances for further development using databases.

    This looks very interesting, but it will still be a while before this technology matures and are ready to use in my opinion. Even if mobile devices in the future have this kind of technology, I wonder how much computing power it will need to be able to handle this kind of connection. With 4G connection at about 10MB/s, the battery on mobile devices last for about 12 hours, I can only image how big our battery is going to be and how much battery life will be at the kind of computing power.

    Interesting stuff. The issue here though in its practicality is the fact that 542 GHz is an extremely high frequency. Such a frequency would require lots of energy as it is a high energy section of the spectrum. So as the above comment states, it would require a ridiculous amount of energy meaning an expensive impractical battery. This would also explain its ability to only travel short distances. With high power, it could go further, but in a real world setting that would not be likely.

    Although this only works for short range distances, i wonder if companies will invest in implementing this technology during the early stages. No longer having to lay down wires and physical mediums throughout the building. This sounds very appealing to me.
